I have a snow drift question.
I'm working with a sawtooth roof and the customer wants to add a canopy, at a lower elevation, at the end of the roof. The sawtooth ridge runs parallel to the edge of the roof where the canopy is to be added.
So how would one calculate the snow drift on the...
To dcarr82775,
Large snow drifts and their possibility of occurring is not my issue. I sense that although it can happen, is it in the 1 in 50 year storm likelihood range? With a ground snow of 5 psf in South Carolina or about 4" is it really within that probability criteria to expect a 3' to...
Sounds like a horrible storm. But would you have designed for it? 13" of snow is about 15-17 psf and San Antonio couldn't be more than 5 psf ground snow. This wasn't a once in 50 year storm from the magnitude of the snow fall. Put it another way, if only 5 psf fell that day, or about 4"...
So I'm doing a job in South Carolina where the ground snow load is 5 psf and I have a canopy resting up against a taller building that's over 300 ft long. When I apply the snow drift requirements of ASCE7 to it I end up with about 45 psf maximum snow. Now something seems implausible here. I...
